Sims Big Brother (Season 12)

The twelfth season of Sims Big Brother premiered on February 5, 2021 and featured 20 houseguests as they vie to be the last houseguest standing and win the $250,000 cash prize.

The season was announced on August 14, 2020 as the first of two season renewals. Casting for the season opened on that day with the premiere of the eleventh season and closed on New Year's Day 2021. Production on the season began in January 2021 and is ongoing.

On January 31, 2021, 20 houseguests were revealed along with the twist that this season would contain the houseguests being split into two separate houses, with the game continuing on a normal schedule for both, while the houseguests are unaware there is a second house next to them.

Set Design and Theme
The twelfth season of Sim's Big Brother became the first to include two separate houses. The houses were custom built so that they would be side by side to each other. The first house was themed after a utopian society, while the second house was themed after a dystopian society.
